Convertible Instruments explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
A price-linked convertible creates a genuine dilemma: convert early and the investor loses its protection if the IPO fails; convert late and the timetable tightens.
The rule on convertible instruments
The session was unambiguous that no outstanding convertible security or instrument capable of altering the equity structure should remain unresolved at the time of filing; any such instrument must be converted or exercised before the red herring prospectus is filed.
The reason follows from the pari passu principle. An instrument that can convert into equity on terms fixed earlier gives its holder a claim on the company's capital that public investors do not have — and the share capital disclosed in the offer document would not be the capital that eventually exists.
The timing problem arises with price-linked instruments. Where an investor's convertible instrument is linked to the eventual listing price, market practice generally defers the conversion itself to the red herring prospectus stage, once the price band has been fixed, rather than to the earlier draft red herring prospectus stage.
The reason: converting too early exposes the investor to the risk if the IPO does not proceed as planned.
Consider the investor's position. It holds an instrument whose conversion ratio depends on the IPO price. Convert at the DRHP stage and the ratio must be fixed on an assumed price — and if the IPO is withdrawn, the investor is left holding equity converted on terms set by an event that never happened, having given up whatever downside protection the instrument carried.
Waiting for the price band means converting on the real number, at a point where the offering is well advanced.
The session is careful not to present this as a complete answer: this practice is not itself free of a residual risk that the offering fails after conversion has already occurred. The RHP stage is late but not certain, and an offering can still be pulled after the price band is announced.
The tax position on converting convertible instruments
No tax arises merely on conversion of compulsorily convertible debentures and compulsorily convertible preference shares, even where the fair value of the resulting equity exceeds the conversion price, since the deeming provision is not attracted to such conversions — a position recently affirmed by the Income Tax Appellate Tribunal in Fairbridge Capital (Mauritius) Limited in 2026.
That is a significant confirmation. Conversion at an IPO commonly produces equity worth far more than the price at which the instrument was subscribed — which is exactly the pattern the deemed income provisions target in other contexts. The holding is that conversion is not a transfer or a receipt but a change in the form of an existing investment.
Two further points on convertible preference shares
| Point | Consequence |
|---|---|
| Bonus shares issued against convertible preference shares | Can attract deemed dividend taxability |
| Convertible preference shares classified as debt for accounting purposes | Will correspondingly affect the company's debt-to-equity ratio for readiness purposes |
The second is easy to overlook because it is an accounting classification rather than a legal one. An instrument that is a share in company law may be a liability under Ind AS — and the leverage ratio that institutional investors examine is built from the accounts, not the register.
How convertible instruments connect to capital structuring
The convertible question sits at the intersection of two readiness pillars. It is a capital structuring item because the instrument affects the debt-to-equity ratio and the eventual share count. It is a promoter structuring item because compulsorily convertible securities are among the limited exceptions to the minimum promoter contribution eligibility restrictions.
A promoter holding a CCPS that will convert at the RHP stage therefore needs to confirm both that the conversion is timed correctly and that the resulting shares qualify towards MPC.
Working through the position
- Identify every instrument capable of altering the equity structure.
- For instruments with a fixed conversion ratio, convert or exercise before the DRHP.
- For price-linked instruments, plan conversion at the RHP stage, and document the residual risk.
- Confirm the debt or equity classification of each instrument under Ind AS and its effect on the leverage ratio.
- Check the MPC eligibility of shares arising on conversion.
Common mistakes
- Filing with convertible instruments still outstanding.
- Converting a price-linked instrument at the DRHP stage.
- Treating convertible preference shares as equity for the leverage ratio.
- Assuming conversion at a gain to fair value is taxable.
